A new and useful prayer scroll mechanism comprising a spool form which is a paper webbing (1) FIG. 1A) is to be unwound, resilient means arranged to act on a said rotary spool (17) of FIG. 2E to rewind the paper webbing (1) of FIG. 1 & 1A thereon, said resilient means comprising a first resilient member (8) of FIG. 2E and a second resilient member (13) of FIG. 2E in which second resilient member (13) of FIG. 2 is arranged to exert a return force on said spool (17) of FIG. 2 & 2E which is less than the return force exerted on said spool (17) of FIG. 2 & 2E by said first resilient member (8) (FIG. 2 & 2E) means (22, 23, 24,25,26,27, all of FIG. 2) inhabiting the return force of said first resilient member (8) during initial rewinding of said spool (17) & paper (1) (FIG. 1 & 1A) so that said second resilient member (13) (2 & 2E) provides the primary return force for spool (17) FIG. 2 & 2E) and wherein said first (8) (FIG. 2 & 2E) and second (13) (2 & 2E) resilient members are operatively connected to said spool (17) FIG. 2) by mount (15) of FIG. 2 and gear train means (3,4,6,7) of FIG. 2. The invention proves particularly advantageous in providing for resilient means, which can exert a reduced return force during the rewinding of the paper (1) (FIG. 1A) for, preferably, a substantial portion of the rewinding thereof. Thus, the degree of visual ability of the paper (1) is reduced during the rewinding of the paper (1) about the spool (17) (FIG. 2 & 2E).
